Systems and methods are disclosed for controlling, diagnosing and prognosing the health of a motorized system. The systems may comprise a diagnostics system, a prognostic system and a controller, wherein the diagnostics system and/or prognostic system employs a neural network, an expert system, and/or a data fusion component in order to assess and/or prognose the health of the motorized system according to one or more attributes associated therewith. The controller may operate the motorized system in accordance with a setpoint and/or a diagnostics signal from the diagnostics system and/or prognostic information. Also disclosed are methodologies for controlling, diagnosing and prognosing the health of a motorized system, comprising operating a motor in the motorized system in a controlled fashion, diagnosing and/or prognosing the health of the motorized system according to a measured attribute associated with the motorized system, wherein the motor may be operated according to a setpoint and/or the diagnostics signal and/or prognosis.

Motorized system integrated control and diagnostics using vibration, pressure, temperature, speed, and/or current analysis

Systems and methodologies are disclosed for detecting faults and adverse conditions associated with electric motors. The method comprises obtaining a current signal associated with the motor, calculating a space vector from the current signal, determining a space vector angular fluctuation from the space vector, and analyzing the space vector angular fluctuation in order to detect at least one fault associated with the motor. Systems are disclosed having a diagnostics component adapted to obtain a space vector angular fluctuation from a current signal relating to operation of the motor, and to analyze the space vector angular fluctuation in order to detect at least one fault in the motor.
